?When putting an purchase, please specify the next if the chain No. is identified.
one. Chain No. and amount of strands
two. Type of sprockets
3. Shaft hole diameter (d) (This can be not required in the event you drill this hole; in this case, drill a hole not exceeding the maximum shaft hole diameter.)
four. Number of teeth
5. Hub diameter (DH) and length (L) (from the situation of non-standard sprockets)
six. Whether the tooth heads are hardened
Specify the following products, in the event the chain No. is unknown
1. Tooth thickness (T)
two. Root diameter (DB) (Caliper diameter (DC) in the situation of odd-number teeth)
